To all whom it may concern e v Be it known that I, Ronnn'r B. KILLooRn,

SELF-HEATING sAn-Isona citizen of the United States, and a resident ofShort Hills, county of Essex, State of New Jersey, have invented certainnew and useful Improvements in Self-Heating Sad- Irons, of which thefollowing is a specification. i a i i My invention relates toselfyheating sad irons in which gas ora similar fuel is the heatproducing medium and has forits Ob", ject to construct an iron ofthiskind in a manner to secure a maximum of efficiency of my improvedsadiron; Fig. 2 is ahorir with a minimumexpenditure of fuel. Myinvention willbe fullydescribed here- Reference is to be had to mgdrawings in wh1ch a e F igure 1 1s a central longitudinal sect on theaccompany zontal section thereof on the line 22 of In the drawings, 5represents the hollow body of the iron which mayl beof any customary andwell known shape and in the example shownis provided with a movablecover 6 pivotally connected to said body at the front end thereof asindicated at 7 is provided with shoulders 12 adapted to bear upon thecover 6 at opposite sides of the slot 8, when said levercextendstransversely of said slot in the position illus trated in Figs. 1 and 3,and thus lock said cover against movement relatively to the body 5. Ahandle 13 of any suitable description for manipulating the iron andmoving the cover is secured to said cover 6 for i11- stance by means ofscrews 14. The upper edges of the side walls and rear wall of the body 5are cut away so that when the cover 6 is in its operative position,openings 15 and 16 are formed respectively at the sides and rear of saidbody for the purpose of promoting a circulation of air within said bodyand of permitting the products of combustionto readily escape. A,channel 17 is formed in the bottom 18 0f the body 5 so as The said cover6 is provided at'its rear end with,

pendent recesses, said partitions inthe example shown being formedintegral with e Specification of Letters Patent. Patented Oct, l IApplication filed Noveniblflii, 1912. Seria1 l To.731,044. a v I ,jectacrosssaid chanueland dividcthe same i i i the bottom of'the body,although this is not absolutely necessary, it being, clearly apparentthat said independent recessesmay be of any desired shape. Airinlets 20extend? through thelbottom ls and have theirouter or inlet ends incommunication with the at mosphereand their inner or outlet ends inconnection with said channcl117 and below? the interior surface of thebottomYlS, the

drawingsillustrating a pair of inlets 20 con ncctedwith each recessofsaid channel 17, this arrangement being only an instance and i notindispensable.

A burnericomprising a tube 21 extends through an opening in the rearwall of the body 5 and hasits forward end securedjin the Ifrontof saidbody in any suitable man ner, as for instance by screw-threading; Thistube 21 is located above and in registry with the channel 17 and isprovided with jet openings 22 directed toward thebottom 18 inoppositcdirections as shown best in, Fig, 3 and further forms part of or isconnected with a mixing tube 23 located exteriorly of said body andpreferably extending at an angle to the vertical. The said mixing tube23 is provided with the usual, air inlets 24and nipple 25,the latter forthe accommodation of the customary flexible tube adapted for connectionwith a source of fuel supply.

When it is desired to use the iron, the said flexible tube is firstconnected therewithand, with the source of fuel supply after which thelocking lever 10 is swung to a position parallel with the slot 8, inwhich condition,

the shoulders 12 have been raised owingto the cooperation of thethreadedstem ,9 and aperture 11 and have been moved out of engagement w1th saldcover. The cover 6 is now free to be swung to an openposition to body toignite the fuel which ityis to :be 1 a understood now issues from thejetopenings 22 of the burner 21. Owing to the fact that these jetopenings 22 are directed toward the bottom 18 in opposite directions theresulting flames will contact with the surface 5 thereof at oppositesides of the channel 17 and will quickly bring said bottom to the heatedcondition required. for use. same time, atmospheric air will enterthrough the air inlets 20 and will pass fromopposite sides into thevarious recesses com posingvv the. channel ,17 and will-thenpass througheach flame so, as to bringabout. a

maximumandv perfectcombustion of:the

fuelissuing from said 'jet openings 22.: The

gPTOClllCtS of combustionwill pass out .of. the openings 15 and 16 atthe .top of the body so that acontinuous and complete circulation issecured withinsaid body. D.ur ingthis.op-,

eration the. partitions 19. serve; to. conduct fuel.

It is to, be understood thatethe various parts of the iron itself aswell-"as-the burner wemay be. of any general.construotionian'd that theillustrationis only an example of my im-; provementand. further. thatthe various changesvmay be .made therein within the scope of, theaclalmswithout departing from the spirit of my invention.

I claim:

1. A sad iron comprising a I hollow.- 1 body- Copier! "Ski-Si patentmay-be obtained for five cents each, by addressing: the Commissioner-ofPatents At the r having a solid bottom provided with air inlet channelsextending transversely through 2. Agsad iron comprisin hollowbody havinga solid bottom provlded with air in let channels extending transverselythrough said solid. bottom toward the center thereof and a row ofindependent recesses com-. inencing at the inner surface of said bottomand extendingdownwardly therein into conhection with said air inletchannels, said row of recesses being located along the longitufdinalmedian line of the body, and a burner adapted for connection'with asource offuel supply located-in said body in registry with itnd abovesaid recesses, the space between said burner and the 1111161" surfaceof-said bottom. being entirely w free .--thr-oughout its length. r I vIn testimony whereof I have hereunto set iny hand in the-presence of.two subscribing witnesses. v
